For the last 16 years, George Yarbrough has been working as a substitute teacher for Kelly Services, a company used by Conway Schools and other districts to contract daily substitutes for teachers and staff.

These days, he spends most of his time at Theodore Jones Elementary School, where he is beloved by the staff and students.

The kids refer to him as "Mr. Ron," and he is no doubt their favorite.

They gathered together Friday afternoon for a school-wide assembly where a secret was revealed.

"Mr. Ron" had received a special honor. After being nominated by the schools' students and staff, he was chosen as Arkansas' Substitute Teacher of the Year.

"He is not just the Sub of the Year for our school...or our district...or for the City of Conway," Principal Tammy Woosley told the students, "He's the Sub of the Year for the whole state of Arkansas."

The room erupted in applause as "Mr. Ron" came to the front in disbelief.

Completely surprised by the award, Yarbrough told the crowd he was humbled by the honor and loves coming to school every day.

"The teachers here make me feel right at home, like I belong here," he said, looking around the room at the students, "and I love getting to be a part of all of your lives. This school is the most special place and right where I want to be."

Yarbrough says his ultimate goal is to set the world record as the oldest substitute teacher.
